3 4-Dibromobenzoic acid（CAS# 619-03-4)

Hoʻolauna

ʻO ka 3,4-Dibromobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:

ʻO 3,4-Dibromobenzoic acid he aniani kala ʻole me kahi ʻala ʻala kūikawā. Paʻa ia i ka māmā a me ka ea, akā hiki ke decompose i nā wela kiʻekiʻe.

E hoʻohana:

Hiki ke hoʻohana ʻia ka 3,4-Dibromobenzoic acid i nā hopena like ʻole a me nā reagents i ka synthesis organik. Hiki ke hoʻohana ʻia e like me kekahi o nā mea no nā diodes māmā māmā (OLED).

Hanana:

Hiki ke loaʻa ka hoʻomākaukau ʻana o 3,4-dibromobenzoic acid ma ka bromination o kahi hopena o ka waikawa bromobenzoic. Hoʻoheheʻe mua ʻia ka ʻakika Benzoic i kahi mea hoʻoheheʻe kūpono a laila hoʻohui mālie ʻia ka bromine. Ma hope o ka pau ʻana o ka hopena, loaʻa ka huahana ma ka kānana a me ka crystallization.

ʻIke palekana: Aia ia i ka ʻāpana o nā halides organik a loaʻa i ka pōʻino i nā kānaka a me ke kaiapuni. E hōʻalo i ka hoʻopili pololei ʻana me ka ʻili a me nā maka, a e hōʻoia ʻoe e hana ana i kahi ʻano keʻena hoʻokolohua maikaʻi-ventilated. Pono e lawe ʻia nā ʻano pale pilikino e like me nā mīkina lima, nā makaaniani palekana, a me ka ʻaʻahu lab i ka wā e lawelawe ai i kēia pūhui. Pono e hoʻolei pono ʻia ka ʻōpala no ka mālama ʻana i nā lula kaiapuni kūloko.
